Re: Rise of Node

and this ...

const fs = require("fs")
const util = require("util")

const writeFile = util.promisify(fs.writeFile)


async function doSave(file, string) {
await writeFile(file, string)
}

Nathan,

you don't have to code async if there is no need for that - a simple

batch

process
that runs in its own instance hasn't other to compete with (so why

async?)-

so you
code that sync - exactly as you are used to.

be aware of that nearly all async functions in node has a sync

counterpart

const fs = require("fs")
fs.readFile <> fs.readFileSync
fs.writeFile <> fs.writeFileSync etc.

But the synch ones aren't supported or updated any more.. which is why IBM
suggest you use asynch.. which is weird. That's like every call to a
program, subprocedure or function is submitted to batch.. sometimes synch
is good.

I already had started a package to make db easier with node, and the
updates to asynch broke that.. what I did (and it's probably wrong) was
make those functions use callbacks and then:

myStuff.getResultSet(sql, function(rs) {
resultSet = rs;
finish();
});

myStuff.getFieldDescriptions(function(cl) {
columnList = cl
finish();
});

function finish() {
if (resultSet && columnList) {
// everything is done... so go ahead here and do whatever
}
}
